[Linux-mips-commits]CVS: linux/arch/mips/kernel traps.c,1.25,1.26

[James S. <jsi...@us...>]

Update of /cvsroot/linux-mips/linux/arch/mips/kernel
In directory usw-pr-cvs1:/tmp/cvs-serv17112

Modified Files:
	traps.c 
Log Message:
Lots of fixes. Dump full TLB when dieing. Don't print message about having sent a FP signal.Only install EJTAG handler if MIPS_CPU_EJTAG in cpu options set. This fixes a memory corruption bug. EJTAG exception handler is located at KSEG0+0x200.
